How can I get the tcl command?

Help
1

If I add tcl to my packages, why is there no “tcl” command added to my path?:wink:

The tcl binary I assume is part of the tcl package?

2

pkgs.tcl and maybe you want pkgs.tclx too

add those to your system however you add other software via nix (configuration.nix, nix profile command, nix-env command, etc…)

3

This is what I’ve done, like all the hundreds other packages I’ve added, but I get no “tcl” binary in my path

  environment.systemPackages = with pkgs; [
tcl
4

sorry, i checked my notes and that should add tclsh command to your path…

does that work for you?

5

ok, but isn’t it normal to have “tcl” in the path and not “tclsh”?

6

without knowing the answer to that i would suggest it might not be normal to have any tcl interpreter in your path in 2024 :sweat_smile:

Good answer;). I’m trying to make emacspeak work and in my troubleshooting, I find this:

export DTK_PROGRAM=espeak
export DTK_TCL=tcl
export DTK_PORT=none
export DTK_DEVICE="espeak"

, so I would assume tcl has to be in my PATH

i think tclsh will work just fine … can you override the environment variable?

I still get the same error when I override it.

export DTK_TCL=tclsh

I also found this:

	If you get an error such as bash: tcl:: command not found, it means that tcl/tclx is not correctly installed on your system. You must get the latest version of either tcl or tclx and install it before Emacspeak will work.

I managed to modify the package, so that I get tclsh as tcl in my path

    #tclsh as tcl
    (pkgs.runCommand "tcl" { nativeBuildInputs = [ pkgs.makeWrapper ]; } ''
                     mkdir -p $out/bin
                     makeWrapper ${pkgs.tcl}/bin/tclsh $out/bin/tcl --argv0 tcl
                     '')

Sadly, still the same situation with Emacspeak, so it must be something else.

Thanks, anyway;)

Someone may have a better sense if you show-your-math–where do you see the above?

I’m not familiar with the package, but when I poke at it in a shell the only references I see to DTK_TCL via recursive grep appear to be documentation (and neither uses “tcl” as in yours):

I found this specific clue on the Ubuntu forum.

Also, Emacspeak works fine if I start Emacs with emacspeak. Like the forum post, I also want to start Emacspeak from inside Emacs. So, I guess it has nothing to do with tcl. It was a false lead;)
